Rotary Jet cleaners

Rotary jet cleanersRotary jet cleaners or impingement cleaners bring high powered cleaning jets to bare on each part of the tank. As the water jet hits the tank wall it explodes outwards dislodging residues by mechanical action. This used of mechanical force via a water jet is far more energy efficient than other methods of tank cleaning meaning that rotary jet cleaners are the most water efficient tank cleaners available.

The jet cleaner will rotate on two axis and will have either 2, 4 or 8 (twin headed) cleaning jets. As these jets rotate they move through a set cleaning pattern that will, over a set period time (the cleaning cycle) ensure that jets are brought to bear on each part of the tank. This results in a very powerful and efficient clean for medium and large tanks.


Rotary jet cleaners are normally only a sensible option for tanks with a diameter greater than 2 meters. Although they can be deployed to clean particularly tough residues in smaller tanks.

Whilst rotary jet cleaners can be used at pressures as low as 3 bar they are most effective when powered by fluid at around 6-10 bar. As such to get the most from these tank cleaners booster pumps that can get pressure to these levels will be required.

Rotary jet cleaners will typically require 125 mm openings to fit through and some of the larger models will need more than this.


Jet cleaners are the most efficient way of cleaning medium and large sized tanks between 2 and 50 meters in diameter. And for tanks much above 6 meters in diameter they are normally the only viable option.

Also for very tough residues the jet cleaner will be the most water efficient system as other cleaning systems will simply take too long to break down the residues. It is true that water and solvents will eventually remove all residues even in low impact systems but it may take a long time. The mechanical force of a high impact jet exploding outwards from the point of impact is a far more energy efficient way of dislodging even stubborn residue. 


Our rotary jet cleaner come in 4 core ranges. Each range has a variety of nozzle sizes and configurations.

Orbitor 2 tank cleanerOrbitor 2 - is our range of 2 nozzle tank cleaners. The two nozzle design maximises the jet power but also means a longer cleaning cycle.

Orbitor 4 nozzle tank cleanerOrbitor 4- is the 4 nozzle range of tank cleaners to give quicker cycle times and the option of 180cleaning


Dual head tank cleanerOrbitor Dual Head - This variation has twin nozzle head with up to 8 nozzles in total. This can be configured to clean between 90o and the full 360o and has the quickest cleaning times.

Storm Blaster heavy duty tank cleanerStormBlasterTM - The Storm Blaster is a heavy duty range of tank cleaners suitable for cleaning very large tanks such and storm water attenuation tanks. It can be configured to clean between 170o and 360o and has a sealed gearbox meaning it can handle fluid with a high particle content.
